For me I would say things started to get strange at move six. He played his move and left the playing hall for more than 10 minutes and this was repeated many times in the next moves. I thought he had some stomach problems! But at some point I decided to go out to see where he is and he was standing outside the toilet room and when he saw me he went back to the playing hall. And then at some point in the game he stopped going out till the game was finished. Multiple extended length “bathroom” breaks and he thought nobody would be suspicious? He probably could have just consulted for one move and nobody would have caught wise.
